It is quite possible to build a tower as tall as the moon on the HIGHER game fields. Building materials - multi-colored slabs of the same size. They appear first on the left, sometimes on the right, moving in a horizontal plane. Your job is to deftly stack the slabs on top of each other, trying to do it as accurately as possible so that you don't have to cut off any protruding edges if the slab moves. After twenty installed elements, the width will be restored again, and the location will change to HIGHER. The goal of the game is to reach the maximum height, which is impossible in reality.
